[texts]The influence of terminal apparatus on telephonic transmission (Volume Bulletin of the Bureau of Standards, Vol. 5, 231-241 (1908) Scientific Paper 101 (S101))
The problem of telephonic transmission has been dealt with by Heaviside, Pupin, and others, and there is little to add to the mathematical treatment of the problem, but the influence of the terminal apparatus has not, in the author's view, been given sufficient attention. The mathematical considerations are then set forth, and the conclusions to be drawn from the author's reasoning are as follows: In general, whatever influence the line may have in distorting a telephonic wave, when the wave rea...

[texts]The capacity and phase difference of paraffined paper condensers as functions of temperature and frequency (Volume Bulletin of the Bureau of Standards, Vol. 7, 495-578 (1911) Scientific Paper 166 (S166))
The capacities and phase-differences of 13 commercial paper condensers by different English, French, German, and American makers were measured at temperatures varying from 10 degrees to 35 degrees , and at frequencies lying between 33 and 1000 cycles per sec. The results of these measurements are presented in 26 curves, which show, for each condenser, the change of capacity and phase-difference with change of temperature, and the variation of the capacity and phase-difference with change of freq...

[movies]Internet Telephony
If you can send data over the internet, why not voice, and if voice, why not phone calls, and if phone calls, why not video phone calls. This program looks at the new technology of internet telephony or voice over IP (VOIP) and video telephony. Demonstrations include PowWow 3.7, Tribal.com, ClassPoint 1.02, Connectix QuickCam 1.0, Logitech's QuickClip, Best Data Smart One, and ClearPhone. Originally broadcast in 1999.

[audio]Macworld 2007 -- Groks Science Show 2007-01-10 - Charles Lee and Frank Ling
For many technophiles, Christmas comes a couple weeks after the fact. At Macworld 2007, we saw a glimpse of what future telephony will look like, but at the same time, developers have products ready to go. On this program, Jon Phillips from MacLife magazine discussed current trends in computing. Also, Kevin Ford talked about advanced telephone systems.

[texts]On the advantages of high spark-frequency in wireless radio-telegraphy (Volume Bulletin of the Bureau of Standards, Vol. 5, 153-157 (1908) Scientific Paper 96 (S96))
Tissot has already pointed out the advantages of high spark-frequency when thermal detectors are employed. The author demonstrates that a high spark-frequency is also advantageous from the point of view of the telephone receiver. Rayleigh's and Wien's results are quoted as showing the rapid increase of sensitiveness with the frequency, and a curve of volt-sensitiveness is given for a pair of 800-ohm Schmidt-Wilckes head telephones of the type used for radio-telegraphic work...

[movies]Internet Video Telphony
After the Internet was around for a few years, people figured out that it was also a phone system and you could use your web connection to do voice and video communications. This program looks at several early examples including PowWow from Tribal Voice, White Pine's ClassPoint, Windows 95 video conferencing, Connectix Web Cam, ClearPhone, stefcam.com, C-U-SeeMe, camgirl.com, and QuickClip. Originally broadcast in 1998.
